Sometimes cancers or polyps bleed. An FOBT checks for blood in your stool. It's a highly sensitive test, which means it can find polyps and cancer. However, sometimes the test can indicate that there's a polyp or cancer when there isn't. This is called a false positive. Or it can miss a polyp that doesn't bleed. Therefore it's commonly used as an initial test before another screening test such as a colonoscopy or a sigmoidoscopy.

Colonoscopy is used to view the inside of your lower digestive tract (colon and rectum). It can help screen for colon cancer and can also help find the source of abdominal pain, bleeding, and changes in bowel habits. The test is usually done in the hospital on an outpatient basis. During the exam, the doctor can remove a small tissue sample ( a biopsy) for testing. Small growths, such as polyps, may also be removed during colonoscopy.
|
|
Virtual colonoscopy is an investigational newer screening method that uses radiation to take pictures of your colon. The pictures are taken using a computed tomography, also called CT, scanner. Unlike the flat pictures from an X-ray, the CT scanner makes a three-dimensional computer image of your whole colon. The test is 90% accurate in finding colon polyps as small as 1 cm. But it is only 25% accurate at finding polyps smaller than 5 mm. So it is not as accurate as a colonoscopy.

|
This year more than 145,000 new cases of colorectal cancer will be diagnosed in the United States. In a large number of those cases, the cancer will be advanced. That means they'll be harder to treat. That also means they'll be more likely to be fatal. The earlier colorectal cancer is found, the easier it is to treat. And that makes a cure more likely. You can even prevent the disease if polyps in the colon and rectum are found and removed before they become cancerous.

A DCBE is also called a lower gastrointestinal series. It is a way to use X-rays to locate polyps and colon cancer. It is a very effective tool for finding large colon polyps and cancer. But it only finds polyps smaller than 1 cm about half the time. So it is a better exam for diagnosing colorectal cancer than for catching it early. Consequently, it is used mainly when you can't have a colonoscopy, but it is not considered standard of care at this time.

A biopsy is a small sample of tissue or fluid taken from the body. This sample can then be studied in a laboratory. Image-guided biopsy allows a sample to be taken from an abnormal mass without the need for surgery. This procedure is done by a specially trained doctor called an interventional radiologist.
